Answer: The distace between midpoints of AP and QB is
.
Step-by-step explanation: Points P and Q are between points A and B and the segment AB measures a, then:
AP + PQ + QB = a
According to the question, AP = 2 PQ = 2QB, so:
PQ =
QB = 
Substituing:
AP + 2*(
) = a
2AP = a
AP = 
Since the distance is between midpoints of AP and QB:
2QB = AP
QB = 
QB = 
QB = 
MIdpoint is the point that divides the segment in half, so:
<u>Midpoint of AP</u>:


<u>Midpoint of QB</u>:


The distance is:
d = 
d = 
A = 1/2 (b x h)
A = 1/2(12.5 x 2.4)
A = 1/2(30)
A = 15
Answer:129
Step-by-step explanation:
Answer:

Step-by-step explanation:
The following information is missing in the question:
We have to find z-score for the given score on this dental anxiety scale: 12, 6
We are given the following information in the question:
Mean, μ = 11
Standard Deviation, σ = 4
We are given that the distribution of score is a bell shaped distribution that is a normal distribution.
Formula:

where x is the given score on this dental anxiety scale.
For x = 12

For x = 6
